(CNN) — Using marijuana at an early age could have long-term consequences on your brain and it may even lower your IQ, according to a new study in the Proceedings of the National Academy of Sciences.
Researchers found that compared to nonusers, people who smoked marijuana starting as early as age 14 have less brain volume, or gray matter, in the orbitofrontal cortex. That’s the area in the front of your brain that helps you make decisions.
“The younger the individual started using, the more pronounced the changes,” said Dr. Francesca Filbey, the study’s principal investigator and associate professor at the School of Behavioral and Brain Sciences at the University of Texas at Dallas. “Adolescence is when the brain starts maturing and making itself more adult-like, so any exposure to toxic substances can set the course for how your brain ends up.”
Maybe the reason we are in so much economic trouble is that our liberal legislators are long time MJ users and have shrunken brains? A shrunken brain could also account for the failure of our local lefties to grasp the beauty of free markets.
Your thoughts? Does marijuana consumption shrink users brains? What are the long term consequences?
